we are looking at changing the way we get root on our network.
in our current system if an admin needs root access he just gets the root password and uses an su.
some of our staff have decided that a sudo to "/bin/sh" will be easer.
some of our staff think a sudo to "su -" will be better.

csp_helper
csp_helper(1) USER COMMANDS csp_helper(1) NAME csp_helper - A collection of caspar helper scripts SYNOPSIS csp_install dir (directory) file (file) csp_mkdircp dir (directory) file (file) csp_scp_keep_mode h ([user@]host) dir (directory) file (file) csp_sucp h ([user@]host) dir (directory) file (file) DESCRIPTION The scripts csp_install, csp_mkdircp, csp_scp_keep_mode and csp_sucp are helpers for caspar(7). These scripts typically are not invoked directly, but via a Makefile which uses caspar. See the notes on csp_PUSH in caspar(7) for information on how to link csp_install, csp_scp_keep_mode and csp_sucp to caspar. install DESCRIPTION csp_install creates the required directory (if needed) and installs the file, preserving timestamps. It uses install(1). install EXAMPLES csp_INSTALL_OPTIONS='--owner=www-data --group=www-data' csp_INSTALL_MODE=ugo=r csp_install /srv/www index.html csp_INSTALL_MODE=u=rwx,go= csp_install /usr/local/sbin mkpasswd install ENVIRONMENT csp_install honors csp_INSTALL_OPTIONS and csp_INSTALL_MODE (default is u=rw,go=r). mkdircp DESCRIPTION csp_mkdircp calls mkdir(1) and cp(1). scp_keep_mode DESCRIPTION csp_scp_keep_mode uses ssh to copy a file to a remote host, keeping its file permission mode. The trick used is a combination of mktemp(1) and mv(1). Useful if you'd like to be sure a file gets installed e.g. group writable, without fiddling with permission bits on the remote host. scp_keep_mode EXAMPLE chmod g+w rc csp_scp_keep_mode root@gandalf /etc/uruk rc scp_keep_mode ENVIRONMENT csp_scp_keep_mode honors csp_SSH ("ssh" by default). sucp DESCRIPTION csp_sucp calls cat(1) from within sudo(1) from within ssh(1). This allows one to copy files to accounts on hosts one can only reach by call- ing sudo on the ssh-reachable remote host. Typically, one wants to install a root-owned file, but one does not want to allow access to the root-account directly from ssh. Typically sudo is used as an extra line of defense. sucp EXAMPLES Some examples: csp_sucp rms@bilbo /etc fstab csp_sucp monty-python commit/ trailer.txt sucp BUGS If NOPASSWD is not set in the sudoers(5) file, and one's timestamp is expired, csp_sucp will forward the sudo password prompt. The given password will be echoed on the console! AUTHOR Joost van Baal-Ili SEE ALSO caspar(7) The caspar homepage is at http://mdcc.cx/caspar/ . csp_helper 20120514 14 mai 2012 csp_helper(1)
